Extension Embed Video

The EmbedVideo Extension is a MediaWiki extension which adds a parser function called #ev and various parser tags like <youtube> for embedding video clips from various video sharing services. It also adds video and audio media handlers to support transforming standard [[File:Example.mp4]] file links into embedded HTML5 <video> and <audio> tags.

This privacy enhanced fork adds a toggleable setting that only loads external content after the user gave explicit consent by clicking the video. Do note that thumbnails are still fetched from the respective service, which results in a connection to an external url. This behaviour can be disabled by setting $wgEmbedVideoFetchExternalThumbnails to false.

Installation

Download

There are three places to download the EmbedVideo extension. The first is directly from its GitHub project page, where active development takes place. If you have git, you can use this incantation to check out a read-only copy of the extension source:

Downloadable archive packages for numbered releases will also be available from the github project page.

Installation Instructions

1. Download the contents of the extension, as outlined above.
2. Create an EmbedVideo folder in the extensions/ folder of your MediaWiki installation.
3. Copy the contents of this distribution into that folder
4. Install FFmpeg, when using the local video handler (enabled by default)

Add the following line to your LocalSettings.php:

Usage

Media Handler

For locally uploaded content the process for displaying it on a page is the same as an image. See the image syntax documentation on MediaWiki.org for complete reference on this feature.

This example would display a video in page using a HTML5 <video> tag.

[[File:Example.mp4]]

To specify the start and end timestamps in the media use the start and end parameters. The timestamp can be formatted as one of: ss, :ss, mm:ss, hh:mm:ss, or dd:hh:mm:ss.

[[File:Example.mp4|start=2|end=6]]

Additionally, a cover image can be set for video files by specifying a cover= key.

[[File:Example.mp4|start=2|end=6|poster=File:LocalFile.png]]

Example

Example of a local file with a custom cover image.

Available options

The following options are available when using the media handler for local files. Options are added to the wikitext like |poster=File:... or |start=2.

• loop
  • Loops the audio / video
• autoplay
  • Automatically plays the file
• nocontrols
  • Disables the control elements

Options only available for video files:

• poster / cover
  • Sets a local image file as the cover of the video
• muted
  • Mutes the audio track of the video (required for autoplay)
• gif
  • Special option that sets autoplay, muted, loop and nocontrols e.g. makes the video behave like a gif

When $wgEmbedVideoUseEmbedStyleForLocalVideos is enabled two additional options are available

• title
  • Title of the video
• description
  • Description shown below the video

Refreshing local metadata

If stored metadata for a local audio or video file needs to be rebuilt, users with the embedvideo-refreshmetadata right can use the Refresh metadata action on the File: page.

This runs an explicit metadata refresh for local EmbedVideo-managed files and is intended for admin use on installations where running maintenance scripts is not practical.

Tags

The EmbedVideo parser function expects to be called in any of the following ways:

#ev - Classic Parser Tag

• {{#ev:service|id}}
• {{#ev:service|id|dimensions}}
• {{#ev:service|id|dimensions|alignment}}
• {{#ev:service|id|dimensions|alignment|description}}
• {{#ev:service|id|dimensions|alignment|description|container}}
• {{#ev:service|id|dimensions|alignment|description|container|urlargs}}

However, if needed optional arguments may be left blank by not putting anything between the pipes:

• {{#ev:service|id|||description}}

Alternatively each parameter can be used in any order as a named parameter. The following parameter are available:

• id
• dimensions
• alignment
• description
• container
• urlArgs
• autoresize
  • Set |autoresize=true to have the embed automatically use all available width of the parent element
• vAlignment
• width
• height
• poster / cover
  • This only has an effect if $wgEmbedVideoRequireConsent is not set to false
• title
  • This only has an effect if $wgEmbedVideoRequireConsent is not set to false

Do note mixing named and unnamed parameters will require you to add all unnamed parameters (and blanks) in the previously mentioned order. E.g. using named id and unnamed description {{#ev:service||||This is the Description|id=abc}}/ {{#ev:service|id=abc|||This is the Description}}

#evu - Embed Video Url

The {{#evu}} parser function tries to extract the service from the host name of an url.

It takes the same arguments as {{#ev}}.

#evl - Embed Video Link

The support for {{#evl}} / {{#vlink}} and <evlplayer> / <vplayer> has been added with version 3.4.0.

The link parser function takes the following arguments:

• id - Video ID
• text - Link Text
• player - ID of the <evlplayer> if multiple exist on a page
• service - Name of the embed service, defaults to YouTube

Named arguments can be passed in any order, unnamed args must be passed in the order defined above.

\ / \

The corresponding player that plays the videos defined by {{#evl}} links.

Note that this implementation differs from EmbedVideo v2.x in the following areas:

• No default content is supported, i.e. text inside the tags
• If no defaultid is provided, the player displays a visible placeholder container (service=videolink) until a link is clicked
  • This restores legacy usage where a single player sits above a list of links
• No style attribute can be set
• Video lists are not supported
• This currently disregards $wgEmbedVideoFetchExternalThumbnails and will fetch thumbnails upon clicking a link

Example

Shows a YouTube embed for the video pSsYTj9kCHE and two video links, one for another YouTube video (NASA Live) and a Spotify track.

When defaultid is omitted, a placeholder player is shown until a link is clicked. You can style this placeholder via CSS, e.g.:

Tip: <evlplayer> accepts either id or player as the player name; if both are provided, player takes precedence.

Examples

SharePoint

For more information on SharePoint embeds see Issue #60.

YouTube Examples

YouTube Example #1

For example, a video from YouTube use the 'youtube' service selector enter the raw ID:

{{#ev:youtube|pSsYTj9kCHE}}

Or the full URL:

{{#ev:youtube|https://www.youtube.com/watch?v=pSsYTj9kCHE}}

YouTube Example #2

To display the same video as a right aligned large thumbnail with a description:

{{#ev:youtube|https://www.youtube.com/watch?v=pSsYTj9kCHE|1000|right|Example description|frame}}

YouTube Example #3

Creating a video list for Youtube. This allows you to queue a set of video in a temporary playlist. Use the youtubevideolist service selector:

{{#ev:youtubevideolist|-D--GWwca0g|||||playlist=afpRzcAAZVM,gMEHZPZTAVc,lom_plwy9iA,BSWYMQEQhEo,EREaWhXj4_Q}}

YouTube Example #4

Using the service name as a parser tag

<youtube>https://www.youtube.com/watch?v=eAORm-8b1Eg</youtube>

YouTube Example #5

Using a local file as an embed thumbnail

{{#ev:youtube|pSsYTj9kCHE|poster=File:LocalFile.jpg}}

YouTube Example #6

Using a local file as an embed thumbnail and specifying a title

{{#ev:youtube|pSsYTj9kCHE|poster=File:LocalFile.jpg|title=Title of the Embed}}

YouTube Example #7

Using named parameters

{{#ev:youtube|id=pSsYTj9kCHE|dimensions=320x320}}

YouTube Example #8

For YouTube to have the video start at a specific time code utilize the urlargs(URL arguments) parameter. Take the rest of the URL arguments from the custom URL and place them into the urlargs.

Please note that not all video services support extra URL arguments or may have different keys for their URL arguments.

https://www.youtube.com/watch?v=pSsYTj9kCHE&start=76

{{#ev:youtube|https://www.youtube.com/watch?v=pSsYTj9kCHE|||||start=76}}

or

{{#ev:youtube|pSsYTj9kCHE|||||start=32}}

or

{{#ev:youtube|id=pSsYTj9kCHE|urlArgs=start=32}}

or

{{#ev:youtube|id=pSsYTj9kCHE|urlArgs=start=32&end=42}}
